Question 227 · LEK · Gout

A 51-year-old patient suffers from recurrent exudates in the left knee, treated by the orthopedic surgeon with repeated joint fluid evacuation and the intra-articular administration of glucocorticosteroids. His family doctor ordered the X-ray of the knee joints which showed linear shadows in the cartilages and triangle deposits in the menisci. The described signs and symptoms suggest:

  1. A. osteoporosis.
  2. B. gout.
  3. C. seronegative spondyloarthropathy.
  4. D. pseudogout caused by calcium pyrophosphate crystals.
  5. E. acute arthritis.
Hint

Linear calcification of cartilage and menisci on X-ray is called chondrocalcinosis; think which crystals produce it.
